Where to use in the

Sill Plate

Where the sill plate is anchored to the foundation wall is a great place for unwanted air and moisture to enter your home. The gap is most likely less than 1” between the concrete on the foundation wall and the pressure treated lumber. These gaps can be filled with Rivenco’s low expansion foams to keep the weather out of your home.

Rim Joist

The rim joist is what supports the floor joists in a building. They are found where the wall meets the basement ceiling. This is a major area of concern in terms of air infiltration. Fill the edges of the rim joist, wall, and floor joists with one of Rivenco’s low expansion foams and start saving money on your heating and air-conditioning bills!

Gas Lines

There are small gaps surrounding gas lines that enter your house. Seal around all pipes that enter the building, and between the main floor and basement.


PVC Pipe Penetrations

In all homes there will be many areas where PVC piping will be entering and exiting the building and living space. Everywhere there is a pipe, fill it with one of Rivenco’s low expansion products. Major offenders of air penetration are the areas around sump pump pipes, and the pipes for septic tanks / waste water.

HVAC Duct Penetrations

Although your HVAC system heats and cools your house, it could be working inefficiently if it is not sealed correctly. Wherever these ducts enter the first floor from the basement, fill the gaps with one of Rivenco low expansion foams.

Window & Door Frames

In basements, windows and doors are often not sealed correctly. In order to seal them you will need to remove any trim, which luckily is often not yet installed in unfinished basements. The areas between windows and doors are notorious for air penetrations, as well as critter penetration. Rivenco products are specifically designed to reduce the amount of critters entering your home by making sure they cannot enter between window gaps.
Remember to check the door around your cold cellar, these doors can be forgotten about in the insulation process.

Wire & Cable Penetrations

Whether it’s for your home’s AC mains electricity or cable TV, there will be gaps around the wire/cable. Fill these gaps that are often forgotten about and start saving!

Central Vac Piping

The areas where central vac piping enter and exit the living area should be sealed off from unwanted airflow. These areas are often between the first floor and basement, and also between the garage and living space.

Plumbing Pipes

The areas where central vac piping enter and exit the living area should be sealed off from unwanted airflow. These areas are often between the first floor and basement, and also between the garage and living space.

Where to use in


Window & Door Frames

When installing windows and doors, be sure to insulate around the outer edge under the trim. You will see noticeable energy cost savings if all windows and doors are sealed correctly.

Electrical Outlets

Behind all electrical outlet covers you will have holes. The areas between the electrical outlet box and drywall should be filled.
Always be sure to turn off the main electrical switch for the areas that are being sealed. Never get insulation inside the electrical box. Let foam cure for full duration before turning power back on.

Central VAC System Piping

The areas where central vac piping enter and exit the living area should be sealed off from unwanted airflow. These areas are often between the first floor and basement, and also between the garage and living space.

Where to use in

Hatch & Door Frames

An often spot that is overlooked when an attic is insulated is the entrance from the living space. Any loose insulation should be removed temporarily and then the space between the hatch and joists should be filled on all four sides.

Gas Lines

There are small gaps surrounding gas lines that enter your house. Seal around all pipes that enter the building, and between the attic and living space.

HVAC Penetrations

Any ducts that may run through the attic are likely letting in unwanted air. All HVAC boots between the attic and living space need to be sealed as well as the flexible insulated HVAC ducts; where they connect to the penetrating boot.


Electrical Lines

The attic is the easiest place for an electrical line or cable to be installed to span the width of a house. The places where it re-enters the living space needs to be sealed in order to prevent penetrating air.

Where to use


Faucets

Faucets are an essential way to get water outside your house. However, they are also a great way for air and critters to get inside your home. Be sure the seal around each faucet outside to prevent and unwanted intrusions.

Dryer Vents

These vents are designed to let air out of your dryer without warming up your house. They are supposed to only allow airflow from the dryer, however it is not uncommon for air to enter from around the vent. Be sure the seal around vents to prevent unwanted air and critters from entering your home.

Exhaust Vents

The vents above your stove are necessary in preventing your house kitchen from filling with steam and smoke. These exhaust vents are designed to pull warm cooking air from your home to the outdoors. Very often unwanted air from outside will enter through the gaps in the exhaust vent. Be sure the seal around vents to prevent unwanted air and critters from entering your home.
